Malware spam: "EBOLA INFORMATION" / "noreply@ggc-ooh.net"

This fake medical email contains a malicious attachment. It's a novel approach by the bad guys, but I doubt that many people will find it believable enough to click.

PLEASE SEE THE ATTACHED CORRESPONDENCE FOR YOUR INFORMATION.

THANK YOU.
Attached is a file 30.03.15 Ebola Virus (2).doc which contains this malicious macro [pastebin] which is contains a lot of girls names as variables (which makes a nice change from the randomly-generated stuff I suppose).

When decoded the macro downloads a component from:

VirusTotal submissions seem to be down at the moment, so I can't tell you what the detection rate is. Automated analysis tools [1] [2] [3] show it phoning home to the following IPs (ones in bold are most likely static, the others look to be dynamic):

37.140.199.100 (Reg.Ru Hosting, Russia)
46.228.193.201 (Aqua Networks Ltd, Germany)
130.241.92.141 (Goteborgs Universitet, Sweden)
46.101.49.125 (Digital Ocean Inc, UK)
122.167.6.68 (ABTS, India)
5.100.249.215 (O.M.C. Computers & Communications Ltd, Israel)

85.255.173.109 (Satnet Ltd, Bulgaria)
217.37.39.235 (BT Broadband, UK)
81.190.50.232 (Multimedia Polska S. A., Poland)
89.228.15.18 (Multimedia Polska S. A., Poland)

According to the Malwr report it drops a whole load of files including what is probably a Dridex DLL.
